'How Long' in the Bible

And Moses and Aaron went in unto Pharaoh, and said unto him - Thus, saith Yahweh, God of the Hebrews, How long hast thou refused to humble thyself before me? Let my people go that they may serve me.

Then said the servants of Pharaoh unto him, How long shall this man become to us a snare? Let the men go, that they may serve Yahweh their God. Not yet, knowest thou, that Egypt is, ruined?

Then said Yahweh unto Moses, - How long have ye refused to keep my commandments and my laws?
